Application
For on/off and floating point control of dampers in HVAC systems. Actuator
sizing should be done in accordance with the damper manufacturer’s
specifications.
Operation
The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with
the actuator will prevent lateral movement. The actuator provides 8” [200 mm]
of linear stroke. The stroke of the gear rack can be adjusted on both sides in
increments of 0.8 in [20 mm] by means of the mechanical end stops. When
reaching the damper or actuator end position, the actuator automatically stops.
The gears can be manually disengaged with a button on the actuator cover.
The actuators use a sensorless brushless DC motor, which is controlled by an
Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls
the actuator’s rotation and provides a digital rotation sensing (DRS) function
to prevent damage to the actuator in a stall condition. Power consumption is
reduced in holding mode.

Provide overload protection and disconnect as required.
Actuators may also be powered by 24 VDC.
Actuators Hot wire must be connected to the control board common.
Only connect common to neg. (-) leg of control circuits. Terminal
models (-T) have no-feedback.
Actuators may be connected in parallel if not mechanically linked. Power
consumption and input impedance must be observed.
